I recently walled my maxima with 2 FI BTL 18's at first i made trim panels to extend the box to the rear doors but they wasnt 100% and now i took the time and extend the trim panls to the b pillars with fiberglass..

My question is my peak freq. was 45hz..im wondering will my peak freq. change any? im hoping it would go down but i dont think so...

I think it might drop....it did in my friends truck when he made panels that extend past the box/wall to seal it off
